You're a good friend of Yuuji. A few days ago he asked you if you could tutor him, since your knowledge on cursed techniques is pretty advanced.

You agreed to this, wanting to help your friend. Only he managed to focus for about an hour, and now he's passed out on his bed.

You decided to let him rest for a while, allowing you to check his notes so far.

A shiver ran up your spine as you felt the atmosphere change, a pair of eyes burning through your skin.
